AChE (nmol/min/mg protein) and ATPase (nmol Pi/mg protein/15 min) specific activity and the inhibition (%) of Meloidogyne incognita with the oxamyl, ethoprophos, and fenamiphos treatments after 48 h post-treatment.
| Treatments | Conc. (mg/L) | AChE specific activity (nmol /min/mg protein) ± SE | Inhibition (%) |
ATPase-specific activity (nmol Pi/mg protein/ 15 min) ± SE |
Inhibition (%) |
|---|---|---|---|---|---|
| Control | – | 536 ± 7.58a | – | 6.59 ± 1.63a,b | – |
| Oxamyl | 5 | 415 ± 12.0a,b | 22.5 | 4.27 ± 1.50b,c | 35.2 |
| 250 | 340 ± 33.7b | 36.5 | 7.27 ± 0.54a | – | |
| Ethoprophos | 5 | 505 ± 50.3a | 5.61 | 1.16 ± 0.22d | 82.4 |
| 250 | 470 ± 21.1a | 12.3 | 1.65 ± 0.22c,d | 74.9 | |
| Fenamiphos | 5 | 469 ± 67.6a | 12.5 | 1.13 ± 0.33d | 82.9 |
| 250 | 349 ± 23.8b | 34.9 | 0.67 ± 0.12d | 89.8 |
Each value is the mean ± SE of 3 replicates, means within the same column followed by the same letter are not significantly different (P ≤ 0.05; Duncan’s multiple range test).
